Incinerator or similar article

ABSTRACT

The incinerator of this invention includes an insulated box having heating means operable to cause combustible products deposited therein to be burned. A grid is provided over the heat means to increase burning of the combustible product. Venting exitways having air filters are provided in the housing to retain exhaust air contaminants. The incinerator is operable to destroy by burning a single combustible product at a time deposited therein.

EDWARD w. HACKER mvemm INCINERA'IOR ORSIMILAR ARTICLE FIELD OF INVENTIONThe present invention relates to an incinerator and more particularly toan incinerator operable to destroy combustible products and to filterexhaust air contaminants and odors.

DESCRIPTION OFTI'IE PRIOR ART Incinerators generally known in the-priorart generally comprise a large combustion chamber into which isdeposited a quantity of combustible products intended to be destroyed.The combustible products to be destroyed are usually accumulated until asubstantial vquantity may be burned at one time, causing an unsightlyand unsanitary collection of waste products. Although some incineratorsare provided with filters, substantial amounts of airborne contaminantsare released into the atmosphere. I

Accordingly, it is an object of the present invention to provide anincinerator in which a single combustible product may be destroyed at atime and thereby avoid accumulations of waste material.

Another object of the present invention is to provide a simplyconstructed incinerator which is inexpensive to operate, and which maybe-placed in convenient locations near the point of disposal, like wastecans or baskets.

A further object of this invention is to provide in combination withincinerating means an air purifying and filter means.

Generally the incinerator of the present invention comprises a boxlikehousing having hinged topand bottom access panels on the housing, anincineratorgrid and a resistence heating coil juxtapositioned in thehousing and an exitway in the housing to exhaust the products ofcombustion. Filters are preferably disposed in the exitway to preventescape of airborne contaminants and odors.

A more thorough and comprehensive understanding may be had from thedetailed description of the preferred embodiment when read in connectionwith the drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of theincinerator of this invention as seen from the top left side and isshown with the access door thereof open.

FIG. 2 is a cross section fragmentary plan view of the invention takengenerally along lines 2-2 of FIG. 1.

FIG. 3 is a cross section elevational view of this invention with one ofthe walls of the housing removed.

FIG. 4 is a cross section elevational view of the invention with anadjacent wall to that wall removed in FIG. removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to thedrawings and more particularly to FIG. 1 which shows the incinerator orsimilar article of the present invention in a top perspective view andgenerally designated by the numeral 10. The incinerator 10 includes aboxlike housing 11 having an access door 12 suitably connected by ahinge 13 at the uppermost terminal side of housing 11 and a panel 14connected by a hinge 15 at the opposing lowermost terminal side ofhousing 11. The sidewalls of the housing 11 preferably include aninsulating material. A sealing gasket (not shown) may be provided aboutthe terminal edges of the housing 11 contiguous with the door 12 to sealthe housing during the incineration process as hereinafter laterdescribed. An intermediate panel 16 integral with the uppermost terminalsides of the housing 11 is provided and disposed so that the panel 16projects upwardly from the housing 11 to engage with the door 12. Inthis manner the quantity of ambient air which may infiltrate the housingmay be limited.

The intermediate panel [6 is provided with a pair of biparting closuresI7 and 17' suitably connected by respective hinges l8 and I8havingsprings I9 and 19' shown to advantage in the cross sectionelevational side view of the FIG. 4.

The biparting closures l7 and "17' are operable to'provideaqcess fordepositing combustible products'in the housingll while providing, at thesame time means 'to safely limit access of hands into the housing 1 1.

The housing] 1 is provided with a latching means 20 which may include acommonly known mechanically timed switch 'v (not shown) electricallyconnected to a resistance heating. coil 21 disposed in the'housing 11.The latching means 20 isen-"' 11 and is more durable.

grid 23 made from ceramic materialsuitable heats toaid in thedistruction of combustible material deposited 'in the housingReferringriow to the fragmentary cross section plan view of I the FIG. 2and the cross section'elevati'onal view of FIG. 3 with one wall-removed,the housing I! is provided with a'iiin- 'termediate wall 24 including avented-exitway 25. The

chamber formed by intermediate wall 24 and the wall of hous-" ing 11provides a draft'plenum which tends to cause the.car bon monoxide gasesto be drawn away from the burning product to permit the product tocontinue to burn. It has been found to advantage in practice toprovide'a charcoal filter in the exitway. Of further advantage is acommonly known electrostatic filter such as 7 shown at *26' and disposedin the chamber 27 formed by the intermediate wall 24 and one of theterminal walls of the housing 1 l which includes an exitway 2 8.

In operation the door l2'is raised and combustible products intended to'be destroyed maybe deposited through closures l7 and 17. onto the grid235When the door 12 is closed andthe latch 20 is engaged with thelock22'on'the door 12. The resistance l'ieating coil-21 and theelectrostatic filter 26 are electrically'energizedfAs the coil isheatedfthe combustible product deposited in the housing'dl is'caused toburn. The heat in the housing-ll causesadraftfromthehousing 11 throughchamber 27 and consequently through the exitway 25, the electrostaticfilter 26, and th'e'exitway 28. The exhaust air is thereby filtered ofcontaminants'and odor. I

The FIG. 4 shows to advantage the hinged panel 14. The panel 14 isprovided withalock'29fshown'toadvantage in FIG. 1. B unlocking the lock29 and opening the panel 14 access to the housing 11 may be had forcleaningand maintenance.

Having thus described in detail a preferred apparatus which embodies theconcepts and principles of the invention and which accomplishes thevarious objects,purp'oses, and aims thereof, it is to be appreciated andwill be apparent to those skilled in the art, that many physicalch'an'gescould be made in the'apparatus without altering the inventiveconcepts and principles embodied therein. Hence, it is intended that thescope of the invention be limited only to the extent indicated in theappended claims.
